Computer operation control and item selection and vending methods and systems

ABSTRACT

A signal is transmitted into a computer in response to an image on a display screen of the computer such that the computer operates in response to the signal; this includes moving a scanner in optical communication with the display screen such that the scanner detects an image (for example, a bar code) displayed on the screen and generates the signal in response. One or more computers may be used, and this may be used for vending a product or other purposes. With or without such scanning, a portion of a store environment may be displayed on a screen of a computer, including showing images of actual products for sale at the store, in which images of actual products are accessed via the computer from a database containing in-store images recorded in the store during a period of non-existent or minimal customer presence in the store. A vending system is also disclosed.

This application is a divisional of U.S. patent application Ser. No.10/127,514 filed April, 2002 now U.S. Pat. No. 7,156,306.

BACKGROUND OF THE INVENTION

This invention relates in part to computer-implemented shopping via acomputer network, such as the Internet. An aspect of this that can beapplied in other contexts is a computer operation control method thatincludes moving a scanner in optical communication with a computerscreen such that the scanner detects indicia displayed on the screen andgenerates a signal in response. A particular application of the presentinvention uses computer screen bar code scanning with a product vendor'spre-existing database of product and bar code information.

Computer communication networks, today primarily the Internet withregard to global access, have facilitated the exchange of informationand created new marketplaces. There have been many on-line retailbusinesses trying to sell products to on-line shoppers; however, atleast some of these on-line retail businesses have failed to prosper orsurvive. Various reasons may account for these difficulties, but one maybe a failure to make the on-line shopping experience easy or comfortableenough for the customer, whereby such businesses have failed to attractenough customers or enough sales volume to survive. Another reason maybe that establishing the business's on-line facility has not beensufficiently integrated with the vendor's pre-existing “brick andmortar” facility.

Many prior on-line vending sites have been list-driven so that a shoppermust read through lists of words describing the goods being marketed.This presents a different shopping experience than the highlynon-textual one a customer has come to use when going to actual“brick-and-mortar” stores. For example, a customer may recognize aparticular product by its packaging but not remember the specific brandname or the species (“Was that ‘original’ style I bought last time, orthe ‘modified’ style? I don't remember that, but I'll recognize it whenI see it.”). Another factor of this “appearance” or “image” type ofshopping is the product placement within the physical store environment(“I don't remember what it was exactly, but it was in this part of thestore next to the widgets.”) To accommodate such non-textual visualshopping techniques, on-line shopping needs to show actual productimages in their actual store configurations (or at least substantiallyso).

Some on-line marketing sites may also be less than ideal for thevendors. Whereas creating and maintaining an on-line vending environmentcan result in an essentially independent entity from the vendor'sexisting business, it would be more efficient to build on pre-existingparts of the pre-existing business in creating the on-line part of thebusiness. That is, there should be convergence rather than divergencebetween the tradition business and the new on-line business. Suchconvergence preferably can reduce at least some computer programmingcomplexity. One way to facilitate such convergence is to visuallyreplicate on-line the store appearance to enhance or create customeridentification with a vendor's physical brick-and-mortar store. Suchon-line convergence should preferably interface with the vendor'spre-existing operating system. For example, many vendors manageinventory through the use of bar code scanning as is well known. When acustomer at a physical store location selects an item and takes it to acheckout counter, the cashier scans a bar code on the product or itspackaging. This enters the transaction in the cash register, and it alsois used by the vendor's background inventory management system. It wouldbe desirable to incorporate a bar code (or other) scanning operation inon-line sales transactions for use in the same manner and with the samepre-existing vendor system as used for the physical store and inventory.

In view of the foregoing shortcomings, there is the need for an improvedcomputer operation control method that can be applied at least toon-line vending transactions. There is the need for a product selectioncommunication method such as may be used in selling products over acomputer network, such as the Internet. There is also the need for animproved method and system for selling or ordering items via a computersystem.

SUMMARY OF THE INVENTION

The present invention meets at least some of the aforementioned needs byproviding novel and improved computer operation control methods, itemselection and communication methods, product vending and orderingmethods, and related vending systems.

One advantageous feature of the present invention is that it providesfor bar code or other indicia scanning directly from a computer screen.In at least some applications, the present invention may reduce oreliminate the need for computer programming used to provide “hotspotting” of screen images or locations that enable mouse pointing andclicking, which actions are replaced at least in part by the scanningfeature of the present invention. The present invention may helpconverge an on-line business with a pre-existing business by enablingon-line use of pre-existing databases keyed or linked to the scannedindicia (for example, bar codes). Interfacing with existing inventorydatabases may speed data access and reduce programming costs. It mayreduce start up costs by using other existing facilities or data, suchas for stores in which bar codes are displayed with products on shelves.

In a particular implementation, the present invention provides on-lineproduct images in visually replicated real store environments so thatcustomers can use their accustomed visual shopping skills instead ofmere textual list shopping. Product images may include the indicia usedas the code to be read in using the present invention. This mayfacilitate a customer's on-line shopping experience and a vendor'sdeployment and maintenance of its on-line site. This also may provideease of product selection by visual search and quick access to moreinformation and selection for inclusion in a “shopping cart” or list.

Although the invention is described in part by reference to on-line useand for product vending, the invention has other applications as well.One non-limiting example includes on-line access to product or otherinformation.

One definition of the present invention is as a computer operationcontrol method comprising transmitting into a computer a signal inresponse to an image on a display screen of the computer such that thecomputer operates in response to the signal. This includes moving ascanner in optical communication with a computer screen such that thescanner detects an image displayed on the screen and generates thesignal in response thereto. In one implementation, the image includes abar code image and moving a scanner includes using a bar code scanner toscan the bar code image. As another example, the image includes analphanumeric character and moving a scanner includes using an opticalcharacter recognition scanner to scan the alphanumeric character. As afurther example, the image includes a graphic element and moving ascanner includes using an optical scanner to scan the graphic element.

The present invention may also be defined in various ways as an itemselection communication method. One of these is as a method of selectingan item using a personal computer, comprising: accessing throughoperation of a personal computer, at the request of a user of thepersonal computer, a database of item information; displaying, through ascreen of the personal computer, in response to the accessed database,information for at least one item, including at least one scannableselector image; and moving a scanner adjacent the screen to opticallyscan the displayed selector image, generating a signal in responsethereto and communicating the signal to the personal computer, therebyselecting the corresponding item. In one implementation, accessing adatabase includes: going via a web browser program stored in thepersonal computer to a predetermined website on the Internet, thewebsite communicating with the database of item information; anddownloading to the personal computer, via the Internet, from thedatabase of item information, the information for displaying through ascreen of the personal computer. This may also comprise sending, inresponse to the signal generated in response to moving the scanner andcommunicated to the personal computer, a communication via the Internetto the website to order the selected item. In another implementation,accessing a database includes using a local storage device in thepersonal computer containing the database of item information.

The present invention has particular use as, but is not limited to, aproduct vending method, comprising: displaying on a screen of a computera portion of a store environment, including showing images of actualproducts for sale at the store and showing scannable images respectivelyassociated with the products; changing the portion of the storeenvironment displayed on the screen until an image of an actual productto be selected and the respective scannable image are shown on thescreen; optically scanning the scannable image shown on the screen togenerate a signal in response thereto; and communicating the signal tothe computer.

Another example of the present invention is as a method of placing anorder for an item, comprising: under control of a client system,displaying on a computer of the client system information identifyingthe item, and sending a request to order the item, including scanning abar code image displayed on the computer of the client system, whereinthe bar code image is related to the item; and under control of a serversystem, receiving the request, and generating an order to purchase therequested item. In one particular implementation, the bar code image hasa width of at least about 4.6 centimeters and a height of at least about1.1 centimeters. In another particular implementation, but again notlimiting of broader aspects of the invention, the bar code image has awidth of at least about 1.6 centimeters and a height of at least about0.5 centimeter.

Still another aspect of the present invention, whether with the scanningfeature or not, is the rendition of the in-store environment. This canbe either real time/live or pre-recorded. Even if pre-recorded, however,the rendition is preferably substantially the same as the real-timeappearance of the store existing at the time a user is seeing the storeimage displayed on his or her computer. Accordingly, the presentinvention also provides a product vending method, comprising displayingon a screen of a computer a portion of a store environment, includingshowing images of actual products for sale at the store, wherein showingimages of actual products includes accessing via the computer a databasecontaining in-store images recorded in the store during a period ofnon-existent or minimal customer presence in the store. The presentinvention also provides a method as just described and wherein theperiod of non-existent or minimal customer presence in the store is alsoone in which a product layout configuration in the store issubstantially the same as the corresponding actual product layoutconfiguration existing in the store at the time of the displaying.

The present invention also provides a vending system, comprising: avendor's database of item information linked to respective selectorindicia information; and a computer site configured to load item andselector indicia information from the product vendor's database, thecomputer site including: a computer having a screen for displayingloaded item and selector indicia information; and a scannercommunicating with the computer for scanning displayed selector indiciainformation shown on the screen and for sending responsive signals tothe computer. This may further comprise an Internet website that isaccessible to the computer site and that communicates with the vendor'sdatabase. As another example, it may comprise a portable memory devicehaving the vendor's database disposed thereon and compatible for usewith the computer.

Therefore, from the foregoing, it is a general object of the presentinvention to provide novel and improved computer operation controlmethods, item selection and communication methods, product vending andordering methods, and related product vending systems. Other and furtherobjects, features and advantages of the present invention will bereadily apparent to those skilled in the art when the followingdescription of the preferred embodiments is read in conjunction with theaccompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a computer 2 having an operatively associateddisplay screen 4 operates in response to or using signals from a scanner6 (“or” as used in this specification, including the claims, isinclusive—that is, meaning any or one or more combinations of the listeditems—unless otherwise specified). This is one example of equipment thatcan be used to implement a computer operation control method of thepresent invention. This method comprises transmitting into a computer asignal in response to an image on a display screen of the computer suchthat the computer operates in response to the signal. This specificallyincludes moving a scanner in optical communication with the displayscreen such that the scanner detects an image displayed on the screenand generates the signal in response.

The image displayed on the screen can be any indicia 8 definingdecodable information. Non-limiting examples of the indicia 8 include abar code (for example, a Uniform Resource Locator image), alphanumericcharacters (that is, letters or numbers), and graphic elements. Graphicelements can include, for example, product images or labels oradvertisements that, when scanned, are matched with a database toprovide information about the products. Thus, in the particularimplementations described herein, the indicia 8 to be scanned areselected from the group consisting of a bar code image, an alphanumericimage, and a graphic image.

These indicia 8 are to be detected using suitable scanning equipmentsuch as, for example, a bar code scanner, an optical characterrecognition scanner, or an optical scanner. In the preferred embodimentsof the present invention, these provide optical or laser scanning of theindicia.

Use of the foregoing enables the present invention to provide an itemselection communication method. One step of this includes displayingitem indicia (for example, a product image) and related scannableidentifier indicia (the aforementioned indicia 8) on a screen of acomputer. Referring to FIG. 2, these indicia are embodied in signalsobtained from a memory 10 of the computer 2 under control of a centralprocessing unit (cpu) 12 of the computer. Another step includes moving ascanner such that the scanner senses the scannable identifier indiciadisplayed on the computer screen. A further step includes communicatinga signal from the scanner to the computer in response to the scannersensing the scannable identifier indicia. From this, a list of productscan be generated in response to communicating the signal from thescanner to the computer. Thus, the signal sent can define informationneeded to generate an order for the item. The signal can be obtained bymanually moving the scanner 6 adjacent the portion of the computerdisplay screen 4 used in displaying the scannable image. In theillustration of FIG. 2, the signal from the scanner 6 can be in anysuitable format, whether parallel for communication via a bus 14 of thecpu 12 or serial for communication via a serial port 16 for the cpu 12.

Whereas FIGS. 1 and 2 illustrate use of the present invention with asingle computer, FIG. 3 represents use with two (or more) computers.Through this aspect of the present invention, an item can be selectedusing a client and server system. This includes displaying on a screen20 of client system 18 information identifying the item and displayingon the screen 20 of the client system 18 a scannable image that is to beused to select the identified item. In response to a user selecting theitem by manually optically scanning the displayed scannable image, suchas in the same manner for computer 2 of FIGS. 1 and 2, a signalidentifying the selected item is sent to a server system 22. The signalsent to the server system 22 preferably defines information needed togenerate an order for the item. Displaying in this example of FIG. 3includes transmitting signals representing the item indicia and relatedscannable identifier indicia over a network from the server 22 to theclient 18, such as over an intranet or local area network or globalnetwork (the Internet, for example). From this, a list of items can begenerated in response to communicating a signal from the scanner to theclient computer and an order generated from the client to the server.Thus, the signal sent to the server system defines information needed togenerate an order for the item. The initial item selection signal can beobtained by manually moving the scanner adjacent the portion of thecomputer display screen used in the client's system in displaying thescannable image.

Whether it includes obtaining the item and identifier indicia locally,such as from a memory in the computer (for example, hard-drive) or oneloaded into the computer (for example, CD-ROM or diskette) or via someexternal source, such as may be connected via local area network or theInternet, for example, the method of selecting an item illustrated inthe drawings comprises accessing through operation of a personalcomputer, at the request of a user of the personal computer, a databaseof item information. In FIGS. 1 and 2, this database is stored on thelocal memory 10; and in FIG. 3, it is the represented database 24 storedwith or apart from the server computer 26 providing the link to theclient computer 18. Non-limiting examples of the database include aninventory control system, a price database, and an order fillingdatabase, each which may be of a type as known in the art. It furthercomprises displaying, through a screen of the personal computer, inresponse to the accessed database, information for at least one item,including at least one scannable selector image. Such method furthercomprises moving a scanner adjacent the screen to optically scan thedisplayed selector image, generating a signal in response thereto andcommunicating the signal to the personal computer, thereby selecting thecorresponding displayed item.

As mentioned above, accessing the database can include use of theInternet. This can include going via a web browser program stored in thepersonal computer 2 or 18 to a predetermined website on the Internet,such as provided using the server computer link 26 which communicateswith the database 24 of item information. This further includesdownloading to the personal computer, via the Internet, from thedatabase of item information, the information for displaying through ascreen of the personal computer. Accessing the database can also includeother techniques, one of which as mentioned above includes using a localstorage device in the personal computer containing the database of iteminformation. Regardless where the item information is stored, acommunication to order the selected item can be sent via the Internet tothe website for a configuration as illustrated in FIG. 3.

Referring to FIG. 4, the local or client computer 2 or 18 typicallyincludes the components shown in FIGS. 1-3 and reiterated generically inFIG. 4. Within the cpu and its memory, however, are the operating system(for example, Windows, Apple) and application and utility programsneeded to perform functions of the present invention and ones as aretypical of a personal computer. Any specific programming, such as(without limitation) for receiving and processing signals from thescanner and communicating with local or remote devices (for example, alocal monitor or a remote Internet site), can be of types known in theart for particular implementations of the equipment. FIG. 4 shows suchprogramming (including data) including a web browser, the itemidentifier database and the scanner interface and signal use software(that is, the software needed to generate a selection or order and tocommunicate that locally or remotely).

FIG. 5 represents types of software needed at the server end for animplementation such as illustrated in FIG. 3. This includes datastorage, signal transmitting and signal receiving software, all of whichcan be of types known in the art for particular equipment and functionsselected.

In view of the foregoing, the present invention as illustrated in FIG.3, and with a more particular illustration of the personal computer 18shown in FIG. 6, can also be defined as an item selection communicationmethod, one step of which includes transmitting signals from a firstcomputer (for example, the server 22) to a second computer (for example,the computer 18) and in response generating at the second computer adisplay showing an image including a visual identifier correlated to arespective item. This method also includes scanning the visualidentifier from a locus adjacent to but exteriorly of the secondcomputer (that is, in the illustrated embodiment, outside the displaydevice, and thus on the exterior of the computer—as contrasted withinteriorly detecting such as via “hot spotting” and detecting cursorlocation). A further step includes receiving at least at the secondcomputer a signal responsive to the scanning. To facilitate productselection when the item is a product for sale, the display generated inthe illustration of FIG. 6 preferably includes some type of view from astore from which the products are actually marketed. This can be acurrent real time view (that is, a live view), or a pre-recorded earlierview of the store; and one may be a primary view and the other asecondary or back-up view. If it is a pre-recorded view, preferably ithas a product layout configuration substantially the same as at the timethe display is generated so that the consumer (that is, the user of thelocal or client computer) sees the configuration substantially as itwould be seen if or when the consumer goes to the actual store.

FIG. 6 illustrates the computer 18 as simultaneously displaying on itsscreen the following: (1) an in-store view 28 visually replicating atleast part of a merchandise section in a store having products for salein merchandise sections across an area of the store, (2) a map view 30having graphical indicia showing the merchandise sections and theirrelative locations across the area of the store, (3) movement controlindicia 32 enabling a user to change images in the in-store view, (4) aproduct information view 34 showing a product selected by the user fromthe in-store view and also showing the scannable identifier that can bescanned to select the item for purchase, and (5) a product selectionarea 36 identifying products selected for purchase by the user. This mayfurther include product name and price information. This may alsoinclude directory indicia 38 identifying locations and productcategories viewable within the in-store view. The in-store view 28 mayinclude showing images of products arranged on shelves in aisles. Themovement control indicia 32 may enable in the in-store view visuallyreplicating continuous movement forward and back and left and rightalong the aisles, up and down the shelves in the aisles, and left andright turns at ends of the aisles. In one particular implementation, thein-store view 28 shows images of products and bar code imagesrespectfully associated with the product images. This viewing areapreferably can be controlled by the user so that a selected portion ofthe in-store view is enlarged to ensure that the respective bar codeimage for a desired product shown in the enlarged portion has aresolution sufficient for the scanner to read.

The in-store images can be live or pre-recorded. As to the latter, oneexample is that in-store images can be taken (by any suitable meansknown in the art, one non-limiting example of which includes a digitalvideo camera) while the store is empty or substantially so (that is,there is non-existent or minimal customer presence in the store, such asat night for stores that close or have fewer customers at that time) andstored for use during the next business day or for a given increment oftime. This allows an up-to-date database of in-store images without theneed to interfere with shoppers' feelings of privacy or usual businessactivities during regular or busier business hours.

From the foregoing, the present invention can also be defined as amethod of selecting an item using a personal computer. This methodcomprises accessing, at the request of a user of the personal computer,the Internet using a web browser program stored in the personalcomputer. It also includes going via the web browser program directly toan item vendor's website on the Internet (such as “vendor.com” in FIG.6). The website communicates with a database of item and bar codeinformation maintained by the item vendor. The item and bar codeinformation includes information representing an actual storeenvironment maintained by the item vendor. Information about at least aportion of the actual store environment and at least one item and itsrelated bar code are downloaded to the personal computer, via theInternet, from the item and bar code information. Images of the portionof the actual store environment, and of at least one item and relatedbar code where actually located in the portion of the actual storedisplayed, are displayed through a screen of the personal computer inresponse to the downloaded information. The method further includesmoving a bar code scanner adjacent the outside of the screen tooptically scan the displayed bar code image, generating a signal inresponse thereto and communicating the signal to the personal computer,thereby selecting the corresponding displayed item. This may furthercomprise sending a communication via the Internet to the website toorder the selected item.

The present invention may also be defined as a particular method ofplacing an order for an item. This particular method comprises, undercontrol of a client system, displaying on a computer of the clientsystem information identifying the item, and sending a request to orderthe item, including scanning a bar code image displayed on the computerof the client system, wherein the bar code image is related to the item.The method also comprises, under control of a server system, receivingthe request and generating an order to purchase the requested item. Thiscan be defined more particularly as a product vending method comprising:displaying on a screen of a computer a portion of a store environment,including showing images of actual products for sale at the store andshowing scannable images respectfully associated with the products. Thismethod also comprises changing the portion of the store environmentdisplayed on the screen until an image of an actual product to beselected and the respective scannable image are shown on the screen.This method also comprises optically scanning the scannable image shownon the screen to generate a signal in response thereto, andcommunicating the signal to the computer. Displaying includestransmitting signals representing the images of actual products andscannable images associated therewith over the Internet to the computeror obtaining signals representing images of actual products andscannable images from a memory of the computer. This method furthercomprises generating a list of products in response to communicating thesignal to the computer. The method can also comprise transmitting asignal from the computer and over the Internet in response tocommunicating the signal to the computer.

Thus, information handling, as provided by the present invention, can beperformed locally via a single computer or in conjunction with one ormore other computers. The scanning can communicate information obtainedfrom the screen of one computer to that computer or to a second computerfrom which a response can be obtained, such as to display on the displayscreen of the locally used computer for further action by the user.

Referring to the various drawings, the present invention also provides avending system. This comprises a vendor's database (for example in thememory 10 of FIG. 2 or database 24 of FIG. 3) of item information linkedto respective selector indicia information. The system also comprises acomputer site configured to load item and selector indicia informationfrom the vendor's database. The computer site includes: a computerhaving a screen for displaying loaded item and selector indiciainformation; and a scanner communicating with the computer for scanningdisplayed selector indicia information shown on the screen and forsending responsive signals to the computer. The foregoing can furthercomprise an Internet website accessible to the computer site andcommunicating with the vendor's database. Alternatively or additionally,it can further comprise a portable memory device having the vendor'sdatabase disposed on it and compatible for use with the computer.

EXAMPLES
